2011 m. Nr. 4 Synthesis and characterization of 3-[(2-{(2-(hydrazinocarbonyl) ethyl]sulfanyl}phenyl) amino]propanehydrazide derivatives
A series of 3-[(2-{(2-(hydrazinecarbonyl)ethyl]sulfanyl}phenyl)amino] propanehydrazide derivatives containing identically ortho-NH/S-substituted benzene moiety were synthesized. The structure of the obtained compounds was proved by combining elemental analysis, mass spectrometry, and 1H, 13C NMR spectroscopy. The 1H/13C 2D (HETCOR), 1H/1H 2D (COSY), DEPT (13C), NOE (1H) NMR methods and molecular modeling (MM2) were used for structure elucidation in more complicated cases. Supplementary sets of resonances, observed in the 1H and 13C NMR spectra of the majority of synthesized compounds, are explained in terms of peculiar structural features.
